[Boliu BL606P audio and video development board] coremark benchmark performance test [Copy link]

 

Preface

According to the evaluation plan, we will conduct performance testing in this article. There are many types of CPU benchmark performance tests, the most common one is coremark, and we will use coremark to conduct CPU benchmark performance tests.

Preparing the code

Download the code

git clone

Only keep the following content and add it to the project app directory

Modify the code

core_portme.h中

#define HAS_PRINTF 0 is changed to #define HAS_PRINTF 1

#define ee_printf printf

Change to

#define ee_printf aos_cli_printf

添加#include "aos/cli.h"

Add #define MAIN_HAS_NOARGC 1

Change FLAGS_STR to "-O0" or "-O3" etc. according to actual situation.

typedef size_t ee_size_t; is changed to

typedef unsigned int ee_size_t;

Add #define ITERATIONS 10000

This value needs to be modified according to the actual situation. If it is prompted that the running time is insufficient, modify and increase this value.

core_portme.c

barebones_clock()

{

#error \

"You must implement a method to measure time in barebones_clock()! This function should return current time.\n"

}

Change to

barebones_clock()

{

//#error \

// "You must implement a method to measure time in barebones_clock()! This function should return current time.\n"

return aos_sys_tick_get();

}

Comment out

#if 0

#error \

"Call board initialization routines in portable init (if needed), in particular initialize UART!\n"

#endif

The following two macros determine the unit of getting time ticks

#define TIMER_RES_DIVIDER 1

# define CLOCKS_PER_SEC (100)

The main function in core_main.c is changed to coremark_main

Change crc16 in core_util.c/coremark.h and other files to core_crc16

Called in the main function

void coremark_main(void);

coremark_main();

test

Set the optimization level

Summarize

The above results are for reference only, because they are closely related to the configuration, such as compiler optimization, main frequency, cache enabling, etc.
